enketo express image does not support PDF generation.

[kryptt]

The docker image as it is currently shipped fails to generate valid PDF files.

1st issue is it is missing x11 and chromium related system libraries;
running apt install chromium-chromedriver inside the instance helped.

after the workaround for the first issue, it fails with

{
    "message": "PDF generation failed: Failed to launch chrome!\n[1127/144000.634343:ERROR:zygote_host_impl_linux.cc(89)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.\n\n\nTROUBLESHOOTING: https://github.com/GoogleChrome/puppeteer/blob/master/docs/troubleshooting.md\n",
    "code": "500"
}

since the docker image never downgrades from the root user which would be good practice anyway.. I placed this in this project but let me know if it is the wrong place to do so.

Thanks!

ok, thank you. i'm not enthusiastic about adding x11 and chromium to the image, but we do want to support pdf generation eventually.
